Question

solve (3/4x + 4/3y)(3/4x + 3/4y)​

Answer 1

$(\frac{3}{4x}+\frac{4}{3y})(\frac{3}{4x}+\frac{3}{4y})\\\\ \frac{3}{4x}(\frac{3}{4x}+\frac{3}{4y}) +\frac{4}{3y}(\frac{3}{4x}+\frac{3}{4y})\\\\\frac{9}{16x^2} +\frac{9}{16xy} +\frac{1}{xy} + \frac{1}{y^2} \\\\\frac{9}{16x^2}+ \frac{1}{y^2} + (\frac{9+16}{16xy})=\frac{9}{16x^2}+ \frac{1}{y^2} +\frac{25}{16xy}$
